# Improvement

SDK users sometimes need to know which JSON-RPC method is being
processed to adjust their implementation, e.g.:
* If the method is `message/send`, they may want to use
`invoke()`/`run()` when calling their LLM API, and
`stream()`/`run_streamed()` for `message/stream`.

# Implementation

Added a `method` field to `ServerCallContext.state`, similar to
`headers`.

# Tests

Added a small test to ensure that method parsing is correct.


Fixes #451

- Adds `make_dict_serializable` to prepare dictionaries for proto
conversion.
- Adds `normalize_large_integers_to_strings` to convert large integers
to strings, preventing precision loss in JS clients.
- Adds `parse_string_integers_in_dict` to convert the integer strings
back to `int`.
- Includes comprehensive unit tests.

# Description

Refactored `tests/client/test_grpc_client.py` and added test cases to
improve coverage for `grpc_client.py`.

- Improved test coverage for `src/a2a/client/grpc_client.py`: 41% → 98%
- Fixed incorrect field checks on the response object in
`grpc_client::send_message`
- Fixed missing `await` call at the correct location in
`grpc_client::send_message_streaming`
- Defined valid `taskId` format (`[a-zA-Z0-9_.-]+`)
